    摘要： A communication system which consists of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master, the others are slave modules controlled by control signals derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

    摘要： For switching or transmitting data packets, one can provide communication systems which consist of several modules —operating in parallel on segments of a packet —to increase speed and handling capacity. One module acts as master, others are slave modules controlled by control signals derived by the master module. It is important to correctly synchronize in each module the data segment and the respective control signal of each packet, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

    摘要： A method is described to operate a crossbar switch comprising a crossbar fabric with N sending and M receiving ports, with port cards connected to at least one sending and/or receiving port each of the crossbar fabric, said crossbar switch further comprising a control unit connected with the port cards via discrete control channel links, wherein C ports are clustered on a single receiving port card so that such a receiving port card in a single time-step can receive up to C data cells from C sending port cards simultaneously. According to said method the control channel links are used to relay up to C acknowledgements between at least one receiving port card and at least one sending port card.

    摘要： A method for scheduling unicast and multicast traffic in an interconnecting fabric performs within each time slot the following steps. First a multicast cell scheduling (61) and independently thereof a unicast cell scheduling (62) is performed. Then, the unicast cell schedule and the multicast cell schedule are merged to a merged schedule (63), wherein in the case a scheduled connection cannot be included in the merged schedule the scheduled connection is included in the merged schedule in a later time slot (66, 63).
